Plant Propagation Techniques

660 Questions

Plant propagation techniques cover both natural and artificial methods of cultivating plants, including micropropagation, tissue culture, and layering. These botanical concepts evaluate how desirable characteristics are multiplied and transferred into new plants. Questions on this topic routinely feature in the biology segment of various state and central competitive exams.

A Correct answer
Explanation

Banana plants are typically propagated using rhizomes, which are underground stems that produce new shoots.

Multiple choice
  1. hybridization

  2. genetic recombination

D Correct answer
Explanation

Micropropagation is a technique of plant tissue culture used to produce large numbers of genetically identical plants from small explants under sterile conditions.

Multiple choice
  1. Antigonon

  3. Ekidea

  4. Amorphophallus

B Correct answer
Explanation

Eichhornia (water hyacinth) is a classic example of a plant that reproduces vegetatively via offsets, which are short, thick runners.

Multiple choice
  1. grafting

  2. paleobotany

  3. embryology

  4. emasculation

A Correct answer
Explanation

In grafting, the scion is the upper part of the plant that is grafted onto the rootstock.

Multiple choice
  1. clonal propagation

  2. induction of somaclonal variations

  3. overcoming hybridization barriers

  4. production of embrayoids

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Embryo culture is often used to rescue embryos that would otherwise abort due to incompatibility between parents, thus overcoming hybridization barriers.

Multiple choice
  1. clean cultivation

  2. embryoid cultivation

  3. bud or shoot tip propagation on culture medium

  4. grafting

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Pathogen-free plants can be obtained through bud or shoot tip propagation on culture medium as it has aseptic environmental conditions.

Multiple choice
  1. Embryogenesis

  2. Embryoid formation

  3. Morphogenesis

  4. Totipotency

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Morphogenesis is the biological process that causes an organism to develop its shape. It is one of three fundamental aspects of developmental biology along with the control of cell growth and cellular differentiation.
